DANIELS, a tions of, say, ten pounds of sand and five of citizen of the United States, and a resident of cement dissolve one-g uartmound of the Yonkers, in the county of Westchester and'mnateria 1n agallon of suitable solvent 5 State of New York,ha\'einvented certain new iquid, and use the muriate of soda b Illsand useful Improvements in Artificial Stone, soivingthree ouncesmmdgadd 1'- of which the following is a specification. ing it to the solution, which is then mixed liIyinvention is an improved artificial stone, with the dry material in 'suilieient quantities consisting of sand, cement, a binding mater lwy l0 rial, as luepg ea og telloiic, and mu j ate of soda, to which in some instances maybe added pearlash, splubl gglass, and al gn. The use of the latter substances, however, is optional. The improved composition consists, essentialiy, of sand, cement, a binding agent, and nmriate of soda, the latter having the effect -of insuring the setting and hardening of the cement, imparting greater body to the material and resulting in a more crystalline product.
